So today I bought a 1976 Honda GL1000 and it has bags and a trunk on the back. When I opened the trunk there were these 2 motorcycle helmets. One has a Harley Davidson bar and shield on it and is black and white. The other I'm not to sure on at all. Its kinda orangeish? with some goldish flakes in it and on the back has a emblem that says El Dorado 77. I really like these helmets because of 1. The way I found them. 2. Because they have some character to them. I don't really know anything else about them. My questions are. 1. Are they collectible/rare 2. How old could they be. If any one knows more info they would like to share on these cool helmets I sure would apprecitate it. I would really like to know what the history is on the El Dorado 77. If it means anything.
